Do the Chevys' have a high idler other than the cold temp sensor when you first start it up? I was told that you could use the cruise control button to get the rpm's up. Is this true or just a wild guess?
Already looked at the Kennedy page.I was just telling everybody if you make a mistake & put the pin in the wrong hole it'll smoke the PC.When I put mine in I couldnt hardly see the pin numbers stamped on the board were the pin goes.I had to count from top to bottom to find the pin hole.Have you had yours apart at all,the pin holes are very close together so you have to be very carefull to get the pin in the right one.Mine is a 01,maybe the newer ones are different.I have never had any trouble with it since I put it in.It sure took a lot of patience to do it.Kinda interesting to see how these darn trucks are built.Sure is getting complicated every year.No comparison to the good ole days ha.Appreciate the comeback on this subject.Take a look at the instructions that are linked in my post...It even gives you pictures of how to do it.
OK I'm confused, I thought the high idle was to keep things cooled down. Is that true or is it to warm things up? Sorry for the noob question..The high idle on the LLY only works when the outside temp is bellow a certain level (iirc 32 degress) and the engine temp bellow a certain level (i don't remember that one).
